This manual contains documentation for libraries which are still part
of the ECL<SUP><I>i</I></SUP>PS<SUP><I>e</I></SUP> distribution, but whose use is deprecated.
Typically, the libraries have been replaced by newer implementation which
provide similar or extended functionality.
The old documentation is provided here mainly to ease the task of porting
existing code to the newer libraries. Documentation for the new libraries
can be found in the <EM>Constraint Library Manual</EM> and the <EM>Reference Manual</EM>.
Here is a short overview of the obsolete libraries and where to find
replacement functionality:
<DL CLASS="description" COMPACT=compact><DT CLASS="dt-description">
<B>fd</B><DD CLASS="dd-description"> The numeric functionality of the finite-domain library is
 subsumed by the <B>ic</B> interval solver library.
 The symbolic domain constraints are provided by the <B>ic_symbolic</B>
 library.
 The branch-and-bound functionality can now be found in more generic
 form in the <B>branch_and_bound</B> library.
<DT CLASS="dt-description"><B>conjunto</B><DD CLASS="dd-description"> Most of this set solver's functionality is available in the
 new <B>ic_sets</B> library.
<DT CLASS="dt-description"><B>ic_eplex, range_eplex</B><DD CLASS="dd-description"> These libraries have now been removed and
 replaced by standalone eplex. Chapter@<A HREF="obsman004.html#eplexstandalone">4</A> describes how
 to port your existing code from ic/range eplex to standalone eplex. </DL>
